Hello all,
Possible noob question.
I have installed a 64 bit gentoo on my intel Pentium D machine.
Now I am reading through /usr/share/portage/config/make.conf.example
My CFLAGS on that machine is the default currently: CFLAGS="-O2 -pipe"
But according to
http://www.gentoo.org/doc/en/gentoo-amd64-faq.xml#cflags I can make it:
-O2 -march=core2 -pipe
Is this entirely necessary? Will it cause a big improvement?
If I do change, how do I recompile everything? (like --newuse for USE
changes?)
Thank you,
Coert Waagmeester
